What causes liver fluke?

Two things are required for infection – animals infected with adult liver fluke (which lay eggs that pass out in faeces) and the presence of tiny mud snails on pasture (in the vicinity of where this faeces lands). These snails thrive in warm, wet conditions and need only a small environment to cause a herd-wide problem, e.g. a leaking water trough/single boggy area on an otherwise dry farm during the summer months.
